Electron microprobe, laser...
- The National Science Foundation (NSF) awarded a $431,158 Project Grant under the Geosciences Program (CFDA 47.050) to the University of Memphis. The grant, awarded on June 15, 2024, will support the acquisition of a micro X-ray fluorescence (μ-XRF) spectrometer for research and education in earth and environmental studies at the university. The μ-XRF instrument will be used to measure and map the spatial distribution of plant-essential nutrients, such as phosphorus, calcium, and potassium, in...
- The University of Tennessee received a $168,267 Project Grant award from the National Science Foundation Division of Ocean Sciences on August 1, 2021 to complete the project by July 31, 2024. The grant supports collaborative research titled "Magmatic and Mechanical Extension of the Challenger Deep Forearc Segment: Insights into Subduction Initiation" under the NSF's Geosciences program (CFDA 47.050). The Geosciences program aims to strengthen understanding of Earth's integrated...
- This $169,286 Project Grant was awarded by the National Science Foundation's Geosciences Program (CFDA 47.050) to the New Mexico Institute of Mining and Technology (New Mexico Tech) to fund a collaborative research project titled "A New Sanidine-Liquid Hygrometer: Experiments, Calibration and Applications." The project aims to calibrate a water-dependent geothermometer based on sanidine compositions, which can be used to determine the conditions of crystallization for important igneous...
- The National Science Foundation awarded a $149,580 Project Grant to the University of Texas at Austin under the Geosciences program (CFDA 47.050) to conduct collaborative research on halogen behavior in the pluton-to-volcanic arc system. Over a three year period ending July 2025, researchers will measure halogen concentrations in intrusive and extrusive rock samples from the Sierra Nevada arc to characterize halogen composition and behavior within the arc magmatic system. Specific products...
- The National Science Foundation (NSF) awarded a $195,944 Project Grant under the Geosciences program (CFDA 47.050) to the University of Tennessee (UT) to conduct collaborative research on the evolution of the Tristan-Gough-Walvis Ridge hotspot system in the South Atlantic Ocean. The project will investigate the changing magmatic processes and interactions between the hotspot and overlying lithosphere during continental rifting and seafloor spreading through geochemical and geochronological...
- The National Science Foundation (NSF) awarded a $385,643 project grant under the Geosciences program (CFDA 47.050) to the University of Vermont & State Agricultural College to investigate magma diversification and mobilization processes in the lower continental crust. The 3-year research project will link field mapping, microstructural analysis, geochemistry, and geochronology to test competing models for how magmas form and are extracted from the deep roots of continental arcs. The...
- This $185,953 Project Grant award from the National Science Foundation's Geosciences Program (CFDA 47.050) supports collaborative research to leverage isotopic compositions of igneous systems to resolve the geometry and distribution of subducted sediment in the southern U.S. Cordillera. The research, led by the University of Texas at El Paso, aims to determine the distribution and geometry of subducted sediment in the continental crust by using igneous rocks as "deep-crustal probes" to...
- This three-year National Science Foundation project grant of $358,891 will fund research and educational activities related to understanding the cycling of halogens like chlorine and fluorine in Earth's early magmas and fluids. Led by the University of Rochester under the Geosciences program (CFDA 47.050), the project aims to advance fundamental knowledge of integrated Earth system processes through targeted studies of ancient zircon minerals. Key deliverables include high-temperature and...
- Cornell University received a $348,300 Project Grant award from the National Science Foundation Division of Earth Sciences to investigate volatile evolution and decompression rates of high-intensity basaltic eruptions. Under the Geosciences program (CFDA 47.050), which supports basic research in integrated Earth system sciences, Cornell will conduct field and laboratory research over three years from July 2023 to June 2026. The university will analyze melt inclusions and reconstruct chemical...
The University of Tennessee received a three-year, $189,910 Project Grant from the National Science Foundation's Geosciences program (CFDA 47.050) to conduct collaborative research building and applying a universal plagioclase oxybarometer using x-ray absorption spectroscopy. The university will measure the oxidation state and oxygen content of plagioclase feldspar crystals from volcanic systems to gain insights into how magmas change as they ascend toward eruption. Researchers will develop new analytical techniques by growing liquidus feldspars over composition and temperature ranges to create standards for x-ray absorption spectroscopy calibration of iron valence state and oxygen fugacity in feldspar. They will apply these calibrations to samples from Mount Shasta, Mount St. Helens, and the Bushveld Complex to examine iron partitioning and oxygen variations. Undergraduate students will characterize the same samples using additional spectroscopic techniques. The research aims to provide new geochemical calibrations and insights into feldspar's role in cation partitioning with melts. The grant supports a postdoctoral researcher and provides underrepresented students opportunities in geoscience lab research.
